  1. 1. Turning waste into resources: Rethinking the way we discard things

    Author : Maria Isabel Ordonez; Göteborgs universitet; Gothenburg University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; HUMANIORA; ENGINEERING AND TECHNOLOGY; HUMANITIES; Solid waste; resource recovery; material loops; waste sorting; user centred design; design with waste; waste collection systems;

    Abstract : Waste is one of the biggest challenges faced by our society. If not handled correctly, waste pollutes our natural environment with devastating results. However, it seems almost unavoidable that our society generates waste. READ MORE

  2. 2. Sustainable Design and Control of Automated Material Handling Systems

    Author : Maziar Mashaei; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed integer leaner model.; CPN tool; Universal design framework; Sustainable production philosophy; Conceptual and detailed design phases; Automated material handling system; Pallet system; Synthesis and evaluation methods;

    Abstract : An automated material handling system is a collection of electro mechanical components, electronics, and computer-based devices that act together to maintain flow of parts and materials in a modern production environment. Material flow is a significant factor in the design of manufacturing plants. READ MORE

  3. 3. Extended Producer Responsibility for Closing Material Loops: Lessons from energy-efficient lighting products

    Author : Jessika Luth Richter; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extended Producer Responsibility; recycling; fluorescent lighting; waste management; Policy Evaluation; LEDs; WEEE Directive;

    Abstract : The transition to a low-carbon economy requires enabling technologies including energy-efficient lighting products. It is increasingly recognized that a sustainable economy is not only low-carbon and energy efficient, but also resource efficient. READ MORE

  4. 4. Towards a Circular Economy with Environmental Product Policy : Considering dynamics in closing and slowing material loops for lighting products

    Author : Jessika Luth Richter; Internationella miljöinstitutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extended producer responsibility; Circular Economy; critical materials; Policy Evaluation; product lifetime; lamps; lighting products; WEEE; Product Policy; ecodesign;

    Abstract : A Circular Economy (CE) can help to achieve the sustainable development goal of responsible consumption and production. Product policies, in turn, can support CE objectives by promoting reuse of products, recycling of materials, and providing ecodesign incentives for more durable products. READ MORE

  5. 5. Energy and material recovery from high-ash waste through pyrolysis

    Abstract : Undoubtedly, the past practices of profit maximisation by all means, which fuelled swift industrialisation and urbanisation, left behind a legacy of non-sanitary old landfills polluting the environment. These, together with active landfills supplied with tremendous streams of waste produced annually, are a loose cannon calling for action. READ MORE
